The wild wheeling and dealing continued on the second day of free agency, and the Rangers were once again big players. This time, rather than signing any marquee free agents, they pulled off a trade with the Columbus Blue Jackets that has the potential to pay huge dividends. General manager Glen Sather shipped defensemen Fedor Tyutin and Christian Backman to Columbus in exchange for forwards Nikolai Zherdev and Dan Fritsche in a deal that should turn out to be ludicrously lopsided in the Blueshirts’ favor.
